Geforce2 TV Out on Gentoo

[Aedan]

Has anyone sucessfully got Geforce2 TVOut working under Linux? I can get a picture up on the TV either with the TV as output, or with TwinView for both TV and Monitor.

However, the colours on the TV are odd, as for some reason the Red and Blue are swapped. Running in TwinView mode, the monitor shows the correct colours, but the TV remains with R and B swapped.

I'm out of ideas right now, and have no idea why this is occuring- any suggestions are welcomed.

Sorry big guy, but this might be a similar problem?

I had TV out working for a GeForce4 - there were big warnings printed on the howto I was reading about conflicts with one or other monitor head (the GF4 I have is dual-headed).

Most important: what version of nvidia drivers are you using? Latest are the 5336 build.

I'm sure you don't need reminding that the GF outputs S-Video, which can be converted to composite or SCART, but that if composite is used, the TV must support it explicitly (it's not the same as RF). You also have to be very explicit in your XF86Config file about which variant of PAL encoding you wish to use, otherwise it'll default to PAL-B. In the UK it's typically PAL-I.
[code] Option "TVStandard" "PAL-I"[/i] I'd imagine you've done that already

Yup, set PAL-I and using SVideo. If the card were encoding to Composite, and the TV looking for SVideo, I'd just get a B&W picture, rather than one with Red and Blue swapped.

SCART is just a connector BTW, not a video standard. As such, SCART supports RGB, SVideo and Composite (and widescreen switching!).

I'll double check which version of the drivers - I just did a gentoo emerge for them about a week ago.

Nope, not even close The problem is simply that everything works correctly, EXCEPT that on the TV anything that's red comes out as blue, and anything that's blue comes out as red. Rather makes people's faces a bit cold.

Are you telling it what monitors are connected? I seem to remember something about the autodetection being a bit strange. You might try:

Section "Device"
   #Dump the following in your card's device section:
   Option "ConnectedMonitor" "TV, CRT" # Or just TV, or "CRT, TV", depending                                                                                        
....

Also, I know it's already been mentioned, but as far as the composite/svideo thing goes, you can force that using Option "TVOutFormat" ("SVIDEO"/"COMPOSITE").

Good luck!

I'm aware of that, but not all SCART devices are created equal. My old TV (inexplicably) swapped the signal and ground pins for each colour channel, so using a "standard" cable resulted in a very weird picture.

I think I might just give up on the GF2 MX card. Only the GF4 cards seem to support overscan, which would be very useful for my application. Guess I'm gonna go out and get a cheap GF4/FX card of some description, unless anyone's got any better ideas.
